Our take on the UFP 3,500 lbs Trailer Bearing & Vault Oil Seal Rebuild Kit (BK2-256-GREASE)

A rebuild kit for trailer wheel hubs rated to 3,500 lbs, pairing bearings with UFP's Vault oil seal. It is aimed at boat trailer owners replacing worn bearings and seals during routine hub service. The Vault seal is the distinguishing part: it is designed to keep oil or grease in and water out, which matters on trailers that get dunked at the ramp. Compared with generic bearing kits, it is a branded, matched set rather than loose parts, so fit is the main reason to choose it.

Questions and answers

What does the kit include?
Bearings and a Vault oil seal for a 3,500 lb trailer hub. Check your hub and spindle against the kit's part number before ordering.
Is it for grease or oil hubs?
The kit is listed for grease service with a Vault seal. Vault seals are built for oil-bath hubs too, so confirm your hub type before use.
Can I reuse my old races?
Only if they are unmarked and unworn. New bearings paired with pitted races will fail early, so inspect and replace races as needed.
How often should trailer bearings be serviced?
Inspect annually and after any long trip or ramp dunking. Water intrusion is the usual cause of trailer bearing failure.
Does it fit my 3,500 lb axle?
It fits hubs that take this bearing and seal size. Match the part number to your spindle and hub, not just the axle rating.
